Xylem to provide UV drinking water disinfection systems in Sweden

US-based water technology provider Xylem has won a contract to supply ultraviolet (UV) drinking water treatment systems for Sweden’s largest UV disinfection project.

The Sydvatten AB Waterworks drinking water treatment plant has been in operation since 1966 in the Scania (Skåne) region in southern Sweden.

Xylem’s UV disinfection systems are expected to complement the currently employed traditional treatment methods at the plant to eliminate bacteria, viruses and parasites and deliver clean and treated drinking water to about 900,000 people across 16 municipalities in the country.

Under the contract, Xylem will supply four WEDECO K-Series UV disinfection systems to upgrade the Sydvatten AB Waterworks facility.

The WEDECO K-Series UV systems were selected for their flexibility, design, low lifecycle costs, negligible environmental impact and ability to handle large volumes of water efficiently while catering to a potential future plant expansion.

Upon completion of the upgrade, the facility will have the capacity to handle a 25% increase in water volume to support future population growth.

Xylem treatment business unit vice president Ron Port said: "Our advanced, sustainable technologies will help to address challenges at Sydvatten AB Waterworks and will deliver chemical-free, clean and safe water for southern Sweden."

The WEDECO K-Series is designed for large-flow drinking water applications, while the UV reactor provides the capacity to
treat large volumes of drinking water with UV light.

In addition, the WEDECO K-Series is a cost-effective solution for low energy and maintenance costs and long UV lamp life.

UV disinfection systems are used in treatment processes for chemical-free inactivation of viruses, bacteria and parasites such as Cryptosporidium and Giardia.

In January, the European Investment Bank announced a loan of $158m to financially support Xylem’s research and development projects in water and wastewater treatment solutions, flow control equipment, analytical instruments and water applications and pump systems for residential, commercial and industrial uses.
